Embodiment 1

[0037] see Figure 1-3 , which is a schematic block diagram of rainwater treatment equipment modified based on septic tanks provided in Embodiment 1 of the present invention, which is used for the drainage system in the diversion system municipal pipeline. The said diversion system drainage system includes rainwater branch pipes, sewage branch pipes and septic tanks . The rainwater treatment equipment transformed based on septic tanks includes: primary rain storage tanks, diversion facilities and treatment facilities.

[0038] Specifically, the septic tank in the existing community can be as follows figure 1 The septic tank shown is installed on the sewage branch pipe (that is, the sewage branch pipe is connected to the septic tank). At this time, the existing septic tank is improved into a primary rain storage tank to realize the secondary utilization of the septic tank and avoid its Abandoned or directly landfilled. The water inlet 101 of the primary rain storage tank imp...

Embodiment 2

[0060] Based on the same inventive concept as in Embodiment 1, Embodiment 2 of the present invention also provides a primary rain storage tank, which is applied to the rainwater treatment equipment modified based on septic tanks described in Embodiment 1. The primary rain storage The tank is improved from a septic tank. The water inlet of the primary rain storage tank is connected to the rainwater branch pipe for the input of primary rain; the water outlet of the primary rain storage tank is connected to the primary rain collection port for the primary rain output; a first switch is provided at the water inlet of the primary rain storage tank, and a second switch is provided at the water outlet of the primary rain storage tank;

[0061] The septic tank is improved in the following way to form the primary rain storage tank: in the flow direction of the sewage branch pipe, the sewage branch pipe passes through the first pipeline at the water inlet pipe of the septic tank septic ...

Abstract

The invention provides septic tank based reconstructed rainwater treatment equipment. The equipment comprises initial rainwater storage tanks which are formed by improving the septic tanks, water inlets of the initial rainwater storage tanks communicate with rainwater branch pipes, water outlets of the initial rainwater storage tank communicate with initial rainwater collection ports, first switches are arranged at the water inlets of the initial rainwater storage tanks, and second switches are arranged at the water outlets of the initial rainwater storage tanks. When the first switches are turned on, initial rainwater in the rainwater branch pipes flows into the initial rainwater storage tanks formed by improving the septic tanks to be stored, and when the second switches are turned on, the initial rainwater in the initial rainwater storage tanks formed by improving the septic tanks flows into the initial rainwater collection ports to be output through the initial rainwater collection ports. The waste septic tanks is transformed and utilized, and the characteristics of low transformation cost, simplicity in implementation and wide adaptability are achieved.

Description

technical field [0001] The invention belongs to the technical field of drainage, and in particular relates to rainwater treatment equipment modified based on septic tanks and a primary rain storage tank used for the equipment. Background technique [0002] At present, many residential areas have begun to carry out rain and sewage diversion renovation, and during the renovation, it has been found that there are many disadvantages in the septic tanks in the residential areas, for example: 1. When the septic tank is performing septic (that is, when it is working normally), it will produce a lot of The biogas content can reach 30 times that of carbon dioxide, and the greenhouse effect caused by it is also very prone to poisoning, explosion and other accidents; 2. The BOD of domestic sewage can be reduced by 20% after passing through the septic tank, and then discharged to the sewage treatment plant The influent concentration of the sewage treatment plant is reduced at the same t...
